Final answer:
From the frame of reference of cyclist 1, the velocity of cyclist 2 would be 3 m/s west.
Step-by-step explanation:
From the frame of reference of cyclist 1, the velocity of cyclist 2 can be determined by considering their relative motion. If cyclist 2 is traveling in the same direction as cyclist 1, their velocities will add up. If cyclist 2 is traveling in the opposite direction, their velocities will subtract.
In this case, since cyclist 2 is moving west, opposite to the eastward direction of cyclist 1, the velocity of cyclist 2 would be subtracted from the velocity of cyclist 1. Therefore, the correct answer is D) 3 m/s west.
